Application of Producibility Measurement
Tool 2

Producibility Measurement
Tool 2 . . .
provides the means for setting and realizing producibility goals; determining if a company can achieve its own or customer producibility goals profitably as it currently operates; and analyzing products currently in production to lower production costs and increase quality.

There are three major factors involved in getting a
piece of hardware out the door of the factory.

The design of the product

The process used to manufacture the product

The materials that make up the product.

Alone, each of these factors produces nothing. But, when they are brought together, a product results. Where the design of the product, the process, and the materials converge, as shown in the diagram, is called the region of producibility.

Producibility Measurement Tool 2 can be used to mathematically evaluate each of the three major factors - design, process, and material - and their interaction in the region of producibility. It provides a means for identifying positive and negative contributions by each of the factors.

It must be recognized that controlling and minimizing the independent
effects of the variables in design, process, and materials involved in making
a product improves quality and enhances producibility. All three must be
controlled for optimum overall results as is indicated by the region of
producibility.

Now, following through with our air-to-air missile example, let's see how
Producibility Measurement Tool 2 can be applied to one of the five circuit
boards that will be contained within the power supply assembly housing.

In our missile we find that in full production the circuit boards must achieve a minimum first-time yield of 85%. Stated another way, at least 85% of the boards would come off the production line without any nonconformance; 85% of the boards would have zero defects - no hidden factory or other rework required - just straight 85% perfection.

With that 85% specification we must determine what is
necessary to achieve that rate. Producibility goals can be set by either the
customer or by the company to meet, among other things, budgets, comply with
performance requirements, adhere to schedules, or to ensure profitability.
